- Compared to endoscopic mucosal resection (EMR), colonoscopic endoscopic submucosal dissection (C-ESD) has the advantages of higher en bloc resection rates and lower recurrence rates of colorectal neoplasms. Therefore, C-ESD is considered an effective treatment method for laterally spread tumors and early colorectal cancer. However, C-ESD is technically more difficult and requires a longer procedure time than EMR. In addition to therapeutic efficacy and procedural difficulty, safety concerns should always be considered when performing C-ESD in clinical practice. Bleeding and perforation are the main adverse events associated with C-ESD and can occur during C-ESD or after the completion of the procedure. Most bleeding associated with C-ESD can be managed endoscopically, even if it occurs during or after the procedure. More recently, most perforations identified during C-ESD can also be managed endoscopically, unless the mural defect is too large to be sutured with endoscopic devices or the patient is hemodynamically unstable. Delayed perforations are quite rare, but they require surgical treatment more frequently than endoscopically identified intraprocedural perforations or radiologically identified immediate postprocedural perforations. Post-ESD coagulation syndrome is a relatively underestimated adverse event, which can mimic localized peritonitis from perforation. Here, we classify and characterize the complications associated with C-ESD and recommend management options for them.

- Iatrogenic perforations are severe complications of gastrointestinal endoscopy; therefore, their management should be adequately planned. A 77-year-old man with a history of diverticulosis underwent a colonoscopy for anemia. During the procedure, an iatrogenic perforation occurred suddenly in the sigmoid colon, near a severe angle among the numerous diverticula. Through-the-scope clips were immediately applied to treat it and close mucosal edges. Laboratory tests showed increased levels of inflammation and infection, and although there were no complaints of abdominal pain, the patient had an extremely distended abdomen. A multidisciplinary board began management based on a conservative approach. Pneumoperitoneum was treated with computed tomography-assisted drainage. After 72 hours, his intestinal canalization and laboratory tests were normal. Though this adverse event is rare, a multidisciplinary board should be promptly gathered upon occurrence, even if the patient appears clinically stable, to consider a conservative approach and avoid surgical treatment.

- Endoscopic submucosal dissection (ESD) is a useful procedure for the treatment of superficial gastrointestinal neoplasm. Compared with endoscopic mucosal resection (EMR), ESD has several benefits, which include resectability of various difficult lesion, accurate histologic assessment of specimen, and lower recurrence rate. However, the risk of procedure- related complications is higher with ESD than with EMR. Moreover, because the colon has a thin wall and limited endoscopic maneuverability, ESD is considered a more challenging and risky procedure when performed in the colon than in the stomach. ESD-related complications are more likely to occur. The significant complications associated with ESD are bleeding, perforation, coagulation syndrome and stenosis, most of which can be treated and prevented by endoscopic intervention and preparation. Therefore, it is important to know how to occur and manage the ESD related complication.

- Background/Aims
Some factors like stent wires, balloon dilatation and use of guide wires seems to increase perforation after self-expandable metal stent (SEMS) placement, but few studies mentioned about the relationship between angulation of malignant stricture and perforation. The present study aimed to confirm that more angular positioning of stents increases perforation.
MethodsThis study was conducted with retrospectively evaluation at Digestive Disease Center, CHA Bundang Medical Center, CHA University. Between January 2002 and August 2011, SEMS was inserted in 130 patients with malignant colorectal obstruction. We studied the difference in the angle of stenosis between perforation and non-perforation groups using fluorography images.
ResultsSEMS insertion was performed in 130 cases of obstruction due to colon cancer. Perforation occurred in eight patients (6.2%) of them. Thirteen cases were excluded from the analysis due to poor fluoroscopic images. Among the eight patients with perforation, the mean stenosis angle was 109.9° compared to 153.1° in the nonperforation group, indicating that the angle was more acute in the perforation group (p=0.016).
ConclusionsThis study shows that more angular positioning of stent increases bowel perforation after SEMS placement for malignant colorectal obstruction.

- Rectal foreign bodies are rare clinical problem in South Korea. Although many
foreign bodies can be extracted safely using endoscopic procedures, some patients
require surgery. Here we describe the case of a 35-year-old male who presented
with a rectosigmoid foreign body, a large carrot measuring 28×7 cm. Sigmoidoscopy
revealed a carrot in the upper rectum extending to the sigmoid colon.
Endoscopic removal failed. The surgeon unsuccessfully attempted to extract the
carrot using various tools without spinal anesthesia. During the extraction attempt,
the patient complained of sudden abdominal pain, and a simple x-ray revealed
pneumoperitoneum. An emergency colotomy and removal of the foreign body was
performed, followed by primary repair of the perforation and a colostomy. Three
months later, the colostomy was repaired.

- Duodenal perforations caused by biliary prostheses are uncommon, but they are potentially life threatening and require immediate treatment. Here we describe an unusual case of duodenal perforation induced by a plastic biliary stent. It masqueraded as a case of cholecystitis and combined systemic upset with a localized peritonitis and fever. Primary endoscopic closure by hemoclips was difficult due to the position of the lateral wall and the complexity of aligning the perforation with the endoscope. To approximate the perforated hole and adherent hemoclips, glue injection and sprayings were successfully performed under cap-fitted endoscopy. The patient recovered without additional complications.

Abstract

- Colonoscopy is a relatively safe tool for diagnosis and treatment of colorectal disease. But colonic perforation during colonoscopy is a severe complication and sometimes becomes a life-threatening condition. It occurs with a frequency of 0.07% among patients having diagnostic colonoscopy and in up to 0.40% of patients having therapeutic colonoscopy. In these cases, surgical treatment is needed but endoscopic repair and conservative management could reduce the need for immediate operations. Endoscopic clipping has been the principal method for non-operative treatment of iatrogenic colonic perforation, but it has important limitations. One of them is that it is technically difficult to clip when the angle of approach is tangential. Here we report a case of an iatrogenic colonic perforation treated with endoscopic band ligation rather than endoscopic clipping, because of approach difficulties.

- The use of colonoscopy is important to prevent colon cancer. Despite the safety of the colonoscopy procedure, the most common complication of a colonoscopy is perforation, which occurs with a rate of approximately 0.3% during diagnostic colonoscopy and occurs with a rate of approximately 1.1% with the use of therapeutic colonoscopy. Surgery is the treatment of choice for most cases of colonic perforation. With the development of endoscopic devices and techniques, conservative treatment of colonic perforation has been reported by the use of endoscopic clipping. We report here a patient with iatrogenic perforation of the sigmoid colon that was caused by diagnostic colonoscopy. The perforation presented as pneumoretroperitoneum, which was successfully treated with endoscopic clipping. (Korean J Gastrointest Endosc 2009;38:348-351)

- Malignant lymphoma of the gastrointestinal tract is a rare lesion that comprises 1∼4% of all the malignant neoplasms of the gastrointestinal tract. The incidence of intestinal T-cell lymphoma is much lower than that of the B-cell type. Intestinal T-cell lymphoma can sometimes carry a very poor prognosis because these patients are often diagnosed at advanced stages. These patients mostly present with nonspecific symptoms such as weight loss, abdominal pain or diarrhea and more frequently with features of small bowel obstruction or perforation. We report here on a case of a malignant small intestinal T-cell lymphoma that presented with perforation. A 51-year-old female had emergency operation because of small bowel perforation and she was diagnosed withperipheral T-cell lymphoma on the post-operative pathologic report.

- Cytomegalovirus (CMV) infection is one of important opportunistic infections and cause significant morbidity and mortality in immunocompromised patients. The colon, stomach, and esophagus are the organs frequently involved with CMV infection. CMV enteritis makes up less than 10% of the CMV gastroenteritis cases, usually presents with diarrhea, bleeding and perforation. Several reports have described patients with acquired immune deficiency syndrome (AIDS) in whom CMV enterocolitis were complicated by ileal perforation, but have been rarely reported in Korea. We report a case of multiple ileal perforation associated with CMV enteritis in 67 years old man who was diagnosed as AIDS later. He complained of hematochezia and abdominal pain. During emergency operation, multiple perforated lesions were seen at the distal ileum above ileocecal valve. Colonoscopic examination revealed multiple shallow aphthoid ulcers at descending colon. CMV enteritis and colitis were diagnosed by microscopic findings of both surgical and endoscopic specimens. He was recovered by antiviral therapy with ganciclovir.

- Placement of an endoprosthesis for billiary obstruction has been advocated as an effective alternative for internal- external drainage catheters or surgical procedure. Endoscopic retrograde biliary drainage (ERBD) is a method of transpapillary insertion and placement of drainage tube in the billiary tree under the direct view of endoscope. Early complications following ERBD that develop within 4 weeks include obstruction of the stent, cholangitis, hemorrhage, acute pancreatitis, and bile duct or duodenal perforation. Late complications include obstruction of the stent and cholangitis, migration of the stent, and intestinal perforation. We expierenced a case of sigmoid colonic perforation following ERBD in a patient with multiple biliary tract stone and cholangitis. Thus we report this case with a brief review of the literature.
